I'd be very interested to know for sure what that was.
I can't see how it can be a mountain range or anything that you would normally expect to see.
It's hard to say from the video how big it is because all that surrounds it is craters. A crater could be inches across or miles across.

There's a lot we don't know about the Moon, in my opinion.
Even the Apollo astronauts initially seemed to think that there were other spacecraft accompanying them.
That's one of the reasons that I think we did probably land on the Moon as 'received knowledge' tells us.
In fact, the best UFO footage comes straight from NASA, taken by Space Shuttle and EVA Suit cameras.
